Self Determination Theory - Motivation Beyond Manipulation

Early research on motivation often took a simplistic view of human nature. Early behaviorists would have argued that motivations are strictly adative. A fun activity that is also rewarded would increase the behavior, not decrease it. People have an innate tendency o pursue basic psychological needs of autonomy, competence and relatedness. Deprive some people of this sense of autonomy by manipulating their choices, and their intrinsic motivation may go down. But what does it mean to be chosen for an action? What is the modern problem with self determination theory?
